Cammalleri, 31, didn’t travel with the Flames for their upcoming two game road swing through Carolina and Nashville. It’s unclear exactly how he got hurt, though he did take a big hit from Pittsburgh’s Tanner Glass during Saturday’s 2-1 loss.

Calgary can ill afford to lose Cammalleri’s goalscoring ability (he has 13 on the year) for any significant length of time. The Flames have just six goals in their last eight games and have been shut out five times, four of those coming on home ice.

Looking ahead, it’ll be interesting to see how significant Cammalleri’s concussion is, and how long he’ll be out for. The pending UFA is expected to be one of the biggest names in play at the deadline.
